Are there any downsides to using setjmp? setjmp is not a good fit for a utility library (I'm guessing that's what you are writing because you said that the parse_file function should probably be a test case). setjmp is just about usable if you control both locations -- all the jump sources and destinations. Jumping out of a library is fraught with problems. -- Ben.
